Stand the radar watch before you stand it at sea.
Marine Radar Lab puts a radar and ARPA console built like the real set, the bridge window and the helm in your pocket. It opens on a watch already under way in the Singapore Strait at night: the radar as a minimap, the wheel and the engine telegraph in your hands. Practise collision avoidance, the helm and the COLREG lights on your phone, the way they are done on the bridge.
iPhone and iPad: coming soon.
The app
A bridge you can train on, every day.
The controls work the way they do on the bridge: the trackball, the EBL and VRM, the trial manoeuvre, ship dynamics fitted to published sea trials, and weather that changes how she handles. Practice in the app is training practice, not sea service.
The home watch
The app opens under way: two hours in the central lane of the Singapore Strait at night, the radar as a minimap, the wheel and the telegraph ready. Everyone can sail the first fifteen minutes.

Radar and ARPA
A console built like the real set: gain, sea and rain clutter, EBL and VRM, ARPA acquisition, AIS, guard zones, trial manoeuvre. Decide-and-act encounters scored from your watch record.
PRO
The bridge window
Look out at the ships you see on radar, with their correct lights by night and shapes by day, under the real sky. Swell, spray, rain and the roll that comes with them.
PRO and MASTER
The helm by hand
The wheel, the telegraph and the autopilot are part of the set in every watch: steer her yourself whenever you want, laden or in ballast, and feel how she answers.
Free on the console
COLREG and SMCP
The full International Regulations with plain explanations and quick checks, free for everyone. See the lights, shapes and sound signals of every vessel in action.

Support Radar Lab
Give seafarers more time on the bridge, before their first real watch.
Many students and aspiring officers get only limited individual simulator time before they join a real vessel. School simulators are expensive and shared, and onboard the bridge is an operational workplace. We built Marine Radar Lab to change that, and we want to take it further: validation with experienced mariners, more devices, more realistic scenarios, and access seafarers can afford. Read the full story.
The bridge should not be the first place where a seafarer finally gets enough simulator time.

Support is a gift that funds development. It does not buy access, a plan, certification or sea time.
